   <span class="function"><strong>maxdb_stmt_bind_param()</strong></span> is used to bind variables for the
   parameter markers in the SQL statement that was passed to
   <span class="function"><a href="maxdb_prepare.html" class="function">maxdb_prepare()</a></span>.
   The string <code class="parameter">types</code> contains one or more characters which specify
   the types for the corresponding bind variables.
  </p>
  <p class="para">
   The extended syntax of <span class="function"><strong>maxdb_stmt_bind_param()</strong></span> allows to give the parameters
   as an array instead of a variable list of PHP variables to the function. If the array variable has not been
   used before calling <span class="function"><strong>maxdb_stmt_bind_param()</strong></span>, it has to be initialized as an emtpy
   array. See the examples how to use <span class="function"><strong>maxdb_stmt_bind_param()</strong></span> with extended syntax.
  </p>
  <p class="para">
   Variables for SELECT INTO SQL statements can also be bound using <span class="function"><strong>maxdb_stmt_bind_param()</strong></span>.
   Parameters for database procedures can be bound using <span class="function"><strong>maxdb_stmt_bind_param()</strong></span>. See the
   examples how to use <span class="function"><strong>maxdb_stmt_bind_param()</strong></span> in this cases.
  </p>
  <p class="para">
   If a variable bound as INTO variable to an SQL statement was used before, the content of this variable
   is overwritten by the data of the SELECT INTO statement. A reference to this variable will be invalid after a call to
   <span class="function"><strong>maxdb_stmt_bind_param()</strong></span>.
  </p>
  <p class="para">
   For INOUT parameters of database procedures the content of the bound INOUT variable is overwritten by the output
   value of the database procedure. A reference to this variable will be invalid after a call to
   <span class="function"><strong>maxdb_stmt_bind_param()</strong></span>.
